TLDR
The design of such a filigrane network requires the very careful control of chemical parameters and the reward is an assortment of different property profiles owing to the richness of possible variations.Abstract:
Air, air, air… and some solid skeleton; this is the basis for an interesting class of materials-the aerogels (shown schematically on the right). Can one therefore speak of "simple" chemistry? The design of such a filigrane network requires the very careful control of chemical parameters. The reward is an assortment of different property profiles owing to the richness of possible variations.read more

Thermal tuning of advanced Cu sol–gels for mixed oxidation state Cu/CuxOy materials
TL;DR: In this paper, the formation of copper gels and aerogels via epoxide addition to CuBr2 in dimethylformamide (DMF) was described, and these materials undergo a rapid gel transition and result in materials that have enhanced mechanical properties when compared with the gels derived from CuCl2.
